Antibody;1MG;IgG1 / kappa;Recognizes Trastuzumab specifically, no cross reactivity with other humanized antibodies.;Anti-Trastuzumab Antibodies (recommended for PK/PD) (TRB-Y1b) are expressed from human 293 cells (HEK293).;This protein . ;Immobilized Trastuzumab at 1 g/mL (100 L/well) can bind Anti-Trastuzumab Antibodies (Cat. No. TRB-Y1b) with a linear range of 0.4-6 ng/mL (QC tested);Immobilized Anti-Trastuzumab Antibodies (Cat. No. TRB-Y1b) at 2g/mL, add increasing concentrations of Trastuzumab in the 10% human serum and then add Biotinylated Anti-Trastuzumab Antibodies (recommended for PK/PD) (Cat. No. TRB-BY5) at 2g/mL. Detection was performed using HRP-conjugated streptavidin with sensitivity of 48 ng/mL (QC tested).
